Coordination and the Haken-Kelso-Bunz Model

by Andrew Wilson in Notes from Two Scientific Psychologists

The first attempt to model coordinated rhythmic movement was the Haken-Kelso-Bunz (HKB) model. This model embodies a particular approach to modelling complex systems that has become common in perception/action research... Read more »

Neuroscience of Murder and Aggression: Epidemiology

by William Yates, M.D. in Brain Posts

This is the second in a five part series on the neuroscience of murder and aggression.  This post will address some key issues in the epidemiology of murder and antisocial personality disorder.  The number of murders in the U.S. has been stable at between 16,000 and 17,000 per year over the 2000 to 2008 time period..  The number peaked at around 24,700 in 1991.  The number has decreased since the early 1990s despite a steadily increasing total U.S. population.The reason for t........

Every patient is an experiment

by PalMD in White Coat Underground

Mrs. Charbin’s blood pressure just kept going up.  She felt fine—no chest pain, no shortness of breath, no headaches—but the numbers put her at risk.  At 55, her risk of developing heart disease at some point in her life is high, and is made even higher by her hypertension.  For each 20 mm Hg rise [...]...

Harvard Confirms Scientific Micsonduct by Marc Hauser

by Greg Laden in Greg Laden's Blog

I am sad to report that it is indeed confirmed by official sources that primatologist Marc Hauser engaged in several instances of what is being termed misconduct while carrying out experiments in his lab.

Dean Michael Smith issued the following letter to members of the Harvard community today: Read the rest of this post... | Read the comments on this post...... Read more »

Differentiating Skill and Luck in Financial Markets with Streaks

by Samuel Arbesman in arbesman.net


Speaking of luck, we just released a paper onto SSRN about luck and skill entitled Differentiating Skill and Luck in Financial Markets with Streaks. This paper, which I worked on with Andrew Mauboussin (a brilliant high school student who worked in our lab this summer), examines the relationship between skill and luck using mutual fund [...]...

Bunches and Antibunches of Atoms: Hanbury Brown and Twiss Effects in Ultracold Atoms

by Chad Orzel in Uncertain Principles

Two papers in one post this time out. One of these was brought to my attention by Joerg Heber, the other I was reminded of when checking some information for last week's mathematical post on photons. They fit extremely well together though, and both relate to the photon correlation stuff I was talking about last week.

OK, what's the deal with these? These are two papers, one recent Optics Express paper from a week or so ago, the other a Nature article from a few years back. The Nature paper inc........ Read more »

Going Nuclear: Closing the Gap Between Radiation and Reason

by Matthew C. Nisbet in Age of Engagement

In a series of posts over at Scientific American's blog CrossCheck, John Horgan describes how several recent articles and books have prompted him to re-evaluate his views on nuclear energy. He specifically recommends Gynweth Craven's Power to Save the World, discusses John Mueller's Atomic Obsession, and describes how Wade Allison's Between Radiation and Reason has challenged his views about the risks of radiation exposure. Horgan's seminal End of Science partly inspired my research focus in gra........ Read more »

Coping Strategies for Men Sexually Abused as Children

by Ultimo167 in Strong Silent Types

O'Leary and Gould (2010) tell us that in an area woefully short of research evidence, what they found in their study was that the adult male survivors of child sexual abuse can learn to cope well with that abuse history. Here, active, practical support from trusted others plays an essential role.... Read more »

Are mutualists monogamists, while antagonists play the field?

by Jeremy Yoder in Denim and Tweed

Two of the most diverse groups of living things on Earth are flowering plants and the insects that make their living from flowering plants. Biologists have long thought that the almost incessant, intimate interactions between plants and plant-eating insects might be the evolutionary cause of each group's spectacular diversity. On a smaller scale, this means that we're interested in the reasons that specific insects and plants interact in the first place—what evolutionary trails leads one insec........ Read more »

Flying Blind

by Journal Watch Online in Journal Watch Online

What you can’t see can kill you. Researchers investigating why some birds are especially prone to hitting power lines have discovered that they literally can’t see where they are flying. That means typical anti-collision efforts, such as hanging warning markers on transmission lines, won’t help fowl that fly blind.
The world’s 65 million kilometers of […] Read More »... Read more »

Will Surgery Cut Diabetes Costs?

by Arya M. Sharma in Dr. Sharma's Obesity Notes

For patients with obesity and type 2 diabetes, bariatric surgery is by far the most effective treatment - it is, indeed, the only form of treatment that can put patients into full long-term remission.
But is surgery really a cost-effective option for health systems looking to contain the immense economic and health burden of diabetes?

Fancy going on a wild plankton chase?

by Vivienne in Outdoor Science

Fancy going on a wild plankton chase around Antarctica this Christmas? In November 2002, a team of scientists did exactly that. They went on a nine-week expedition around the Southern Ocean – the ocean surrounding Antarctica – looking for a lush marine oasis awash with marine life and previously overlooked by science. Among their trials and tribulations, Dr Walter Geibert [...]... Read more »

Adenoviruses and the occupied sign

by iayork in Mystery Rays from Outer Space

“Adenovirus” (by Mapposity) There are two aspects about virology that constantly amaze me: How much we know about viruses, and how little we know about viruses. Adenovirus research offers examples of both. Adenoviruses are probably among the best-studied virus groups.1 We really do know an amazing amount about them. But it was only last year [...]...

Coiling bacterial DNA

by Grant Jacobs in Code for life







A chain of proteins hold bacterial DNA in a compacted spiral.

In earlier articles, I’ve mentioned in passing how the enormous length of DNA in our cells is fitted into [...]... Read more »

Evolution of Colour Terms: 8 Embodied Relationships

by Sean Roberts in A Replicated Typo 2.0

In a series of  posts, I’ve been discussing constraints on the evolution of colour terms.  In the last post, I discussed Perceptual Warping.  Here, a further adjustment to the assumptions about perceptual space is suggested.
The assumption that all perceptual spaces are the same may be unrealistic and may favour Universalism (see Levinson, 2000).  To begin with, . . . → Read More: Evolution of Colour Terms: 8 Embodied Relationships... Read more »

Synthetic ‘cradle’ boosts hope of stem cell therapies
